A mobile speed camera van caught a motorbike travelling at more than twice the speed limit on a busy road.

The 45-year-old Cheshire biker was riding his BMW at a staggering 136mph on the A5 at Dinmael near Corwen last May when he was snapped by police officers stationed in a mobile GoSafe camera van.

The speed limit at Dinmael is 60mph.

A North Wales Police spokesman said the man was ordered to pay £325 after admitting charges of speeding and driving without due care and attention.

Figures obtained by the Daily Post under a Freedom of Information Act request revealed he was one of 37,837 drivers found to be speeding by the mobile patrol vans in 2014.

The figure is up on the 36,998 drivers found speeding in 2013 and the 33,846 drivers in 2012.

But the numbers are significantly lower than the 53,908 drivers found speeding by the mobile vans in 2009 when North Wales Police were still led by former Chief Constable Richard Brunstrom who had targeted speeding motorists.

The latest statistic has contributed to a "slight decline" in motorists caught exceeding the speed limit in North Wales between 2009 and 2014.

A total of 1,663 drivers were prosecuted in the courts last year compared to 2,090 in 2013 and 2,994 in 2009.

The numbers released by the force also revealed 22,389 speeding drivers completed speed awareness courses.

This was the highest figures in the past six years.

A motorist, found driving at 34mph in a 30mph zone in Menai Bridge last October, accepted an offer to attend a speed awareness course held in Bangor.

Asking not to be identified the driver said he paid £85 for the course instead of a fine and points on his licence.

“I learned a lot from the course and it has certainly made me more aware of the speed limit, especially when I approach built-up areas,” he said.

Chief Inspector Darren Wareing said: “We have seen a slight decline in offences being detected.

“There are a number of reasons for this which include engineering factors, educational inputs and of course enforcement.

“To see the decline in speeding detections is really encouraging.

“Our tactics remain broadly the same which include the use of fixed and mobile cameras in areas of community concern and where there is a history of collisions, the use of hand held devices and the use of both marked and unmarked traffic vehicles.

“I must stress that enforcement of the law is done with a single aim and this is to influence future driving behaviour so that the devastating effects of a serious or fatal collision can be avoided.

“The vast majority of the driving public in North Wales conform to the laws and drive wholly appropriately.”
